Introduction to CBL reporting for financial companies

The Central Bank of Luxembourg is in charge of collecting data and statistics from Luxembourg financial services and institutions. Along with the adoption of new rules in 2014, amending the BCL regulation of April 2011, many entities have to deliver a monthly report to the Central Bank of Luxembourg.

For the uninitiated, it may be complicated to navigate through the codifications and terminologies to be used. In order to fill-in and file accurate reports, mastering the above-mentioned rules are essential.

Duraton: 4h

Language: Available in English
